Nearly half of all large-scale experiments in Tanzania, using a new insect repellent treatment for malaria in children, according to The Lancet, raises hopes for new weapons in the fight against the old archer.
Nets have been instrumental in the great progress the world has made in recent decades against malaria, where millions have been saved.
But progress has slowed down in the last few years, in part because mosquito-borne diseases are increasingly resistant to pesticides used on existing nets.
In 2020, 627 000 people died of malaria, mainly children in sub-Saharan Africa.
Currently, researchers at the London School of Hygiene and Tropical Medicine in the UK (LSHTM), the National Institute for Medical Research and Kilimanjaro Christian Medical University College in Tanzania, at the University of Ottawa in Canada have shown a new insect – of first. within 40 years – is both safe and effective in experiments that are not really random.
This net, treated with chlorfenapyr and pyrethroid, the most commonly used chemical, reduced the incidence of malaria compared to the current net by 43% in the first year and 37% in the second year the experiment.
The study involved more than 39,000 families and included over 4,500 children aged 6 months to 14 years.
This net, developed by BASF in Germany and LSHTM, is a little more expensive than the current net, at around $ 3 per unit, but the researchers said the cost of saving and preventing more cases than the previous one has increased.
Chlorfenapyr acts differently than pyrethroids, suppressing mosquitoes effectively by making the wings less susceptible to infection, and therefore weeds, spreading the disease.
This chemical was originally designed to fight malaria 20 years ago, and has been used to prevent suffering since the 1990s.
Health has already approved the use of the new net, but the experiment, approved by the British government and the Wellcome Trust, could lead to widespread recommendations for their use.
“This is the first evidence of a real-life situation,” Dr Jacklin Mosha, research director of the National Institute for Medical Research, Tanzania, told Reuters.
Along with advances in anti-malarial drugs, approved by the World Health Organization last year, the group said the net could be another tool in the malaria service box.
However, they warn that it is important to ensure that mosquitoes do not develop a rapid resistance to chlorfenapyr, if it is used in many places.
